Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric pot. The present invention relates to an electric pot capable of pouring a content liquid to the outside of a body through a pouring pipe line leading to an inner container.

[0002]

2. Description of the Related Art A conventional electric pot of this type is the actual one 61
There is one disclosed in Japanese Unexamined Patent Publication No. 122745. This is an inner lid that opens and closes the opening of the inner container that is detachably attached to the body, and an inner lid that is located outside the inner lid and is provided on the body to open and close the inner lid at the upper end of the body. The inner lid is integrally provided with a spouting line for pouring out the liquid content in the inner container to the outside of the container, and the inner container is sealed with a transparent heat-resistant glass plate. When the inner container side liquid volume display window sealed with a material is provided and the inner container is housed in the body, the inner container side liquid volume display window is provided on the body. The liquid amount in the inner container can be seen through so as to face the volume display window.

As a result, the inner container can be taken out of the body having the heater and handled independently, which is convenient for cleaning the inner container, and the inner container can be attached and detached, but even when it is accommodated in the body. It is convenient to use since the liquid volume of the content liquid can be seen through from the outside of the body through the two liquid volume display windows on the inner container side and the body side.

[0004]

However, in the above-mentioned conventional structure, even if the outer lid is opened, only the inner lid having the spouting conduit is exposed. If this is not removed, the inner container is detachable. Since it is not possible, it is inconvenient to attach and detach the inner container. Further, since the removed inner container does not have a pour-out conduit, it cannot be pour out using it, and can only be detached for cleaning or the like. Furthermore, two liquid volume display windows, one on the inner container side and one on the body side, are required to display the liquid volume. The display window on the inner container side is an opening for the window provided on the inner container and a transparent window for closing this. Since the glass and the sealing treatment between the opening and the glass are required, the structure is complicated and the cost is high. Moreover,
The overlap of the two liquid volume display windows, inside and outside, allows the liquid volume of the content liquid in the inner container to be seen through, but if the content liquid and the liquid level of it are not within the window range, the appearance is almost the same regardless of whether or not the inner container is present. Therefore, there is an inconvenience that it is impossible to determine whether or not the inner container is attached. Further, it sometimes happens that the outer lid is closed but the inner lid is not attached, and even if the pump is operated, the content liquid cannot be poured out, which is inconvenient to use.

An object of the present invention is to solve the above problems, and to provide an electric pot having a simple structure in which the inner container can be easily attached and detached and can be used conveniently, and moreover, whether the inner container is attached or detached can be easily discriminated. The task is to do.

[0006]

In order to achieve the above object, the present invention accommodates an inner container so that it can be removably mounted in the body, and an outer lid and an inner container for opening and closing the opening of the inner container in the body. A heater for heating the content liquid inside is provided, and a pump for pumping the content liquid out of the vessel by pressurization from a pressure pump provided on the outer lid is provided outside the inner container. It is characterized in that a part of the inner container is a transparent liquid amount display portion which faces the liquid amount display window of the container when the container is housed in the container.

[0007]

According to the above construction of the present invention, when the inner container is detachably accommodated in the container, the content liquid can be heated by the heater on the side of the container to boil or keep warm and to store hot water. When the lid is closed, the upper end of the container is closed together with the opening of the inner container, and the pressure liquid provided in the outer lid pressurizes the content liquid in the inner container and the liquid is supplied through the pumping pipe provided in the inner container. It can be surely poured out of the body. When the outer lid is opened, the upper end of the body is opened together with the inner container, and the inner container is exposed so that it can be attached and detached as it is. In addition, the taken-out inner container can be washed by itself, and it can be conveniently used because it can be poured out to the outside of the vessel through the pump by tilting it toward the side having the pump. Moreover, since the transparent liquid amount display portion of a part of the pumping pipe faces the liquid amount display window provided on the body when the inner container is housed in the body, it is seen through from the outside of the body.
While the liquid volume display window is transparent, it is possible to easily determine from the outside of the body whether the inner container is attached or detached by whether or not there is a pipe-shaped liquid volume display section with a unique appearance compared to the liquid volume display window. The amount of the content liquid should be displayed outside the body as before according to the presence or absence of the content liquid that should flow into the same level as the inner container and the position of the liquid surface. Further, since these indications can be achieved by one window which does not require a seal on the body side and a simple structure in which at least a part of the pumping pipe is made transparent, the cost can be reduced as compared with the conventional one. Can be planned.

Further, the pumping pipe 9 has a rising portion, which is a part thereof, as a liquid quantity display portion 9a formed of a transparent tube, and a liquid quantity display window 11 provided in the body 1 when the inner container 7 is housed in the body 1. I am trying to face it. The liquid volume display window 11 of the body 1 is a resin panel 10 extending from a shoulder member 4 fitted from the upper end to the front of the outer body 2.
Through the transparent plate fitted into the elongated opening 25 so that the inside of the body 1 can be seen through.
The presence or absence of the inner container 7 can be discriminated from the outside of the body 1 depending on whether or not the liquid volume display portion 9a is accommodated in. At the same time, when the liquid amount display portion 9a is located, the liquid amount of the content liquid can be displayed outside the container 1 depending on the presence or absence of the content liquid flowing into the inner container 7 at the same level and the position of the liquid level. To Of course, although the liquid volume display portion 9a is transparent, it has a pipe shape and has a peculiar appearance to the liquid volume display window 11 of the container 1, so that the presence or absence thereof can be easily confirmed through the liquid volume display window 11, It is easy to determine whether the inner container is attached or detached based on the presence or absence of this.

In this embodiment, the pumping pipe 9 is a short one that opens upward at the mouth of the inner container 7, and the inner container 7 is taken out.
As shown in FIG. 1 and FIG. 3, the outer lid 6 is provided so that the pumping pipe 9 does not overhang when it is handled.
In the front part of the pipe, there is a discharge passage pipe that can be connected to and separated from the pumping pipe 9.
20 is provided so that when the outer lid 6 is closed, this is connected to the upper end of the pumping pipe 9, and the content liquid that is pressurized and poured out through the pumping pipe 9 is placed at a predetermined position on the upper front part of the body 1. It is possible to pour in a predetermined direction outside the body 1 in a predetermined direction. The discharge passage pipe 20 has a built-in water shutoff valve 18 in the middle of a fall, and one end thereof is connected to a silicone rubber mouth packing 16 provided on the inner lid 8. The mouth packing 16 is inserted into the opening 8a of the inner lid 8 and fitted to the pumping pipe 9 on the inner container 7 side.
When the inner lid 8 is closed, it is pressed against the upper end of the pumping pipe 9 at the time of connection with the pumping pipe 9 to prevent leakage of the content liquid at both connection parts.

The other end of the discharge passage tube 20 is projected downward from the beak-shaped projection 6a on the front portion of the outer lid 6, and is provided on the front portion of the shoulder member 4 of the body 1 when the outer lid 6 is closed. A pipe cover 4a
The content liquid poured out from the pumping pipe 9 is opposed to the liquid injection guide pipe 21 inside, and is poured into the liquid injection guide pipe 21 in a state of being opened to the atmosphere so that liquid can be stably injected.

Thus, of the pumping pipe 9, the discharge passage pipe 20, and the liquid injection guide pipe 21 which mainly constitute the liquid content discharge passage, the discharge passage pipe 20 is integrated with the lid side, and the discharge guide pipe 21 is also provided. Remains on the container side, and the pumping pipe 9 is integrated with the inner container 7 and can be freely inserted into and removed from the inner wall 3 of the container 1 as shown in FIG. Then, the discharge passage tube 20 can be detachably attached to the body 1 together with the outer lid 6.
